Semi-Invariant Submanifolds of Almost $\alpha$-Cosymplectic $f$-Manifolds

Abstract

In this paper, we have and study several properties of semi-invariant submanifolds of an almost $\alpha$-cosymplectic $f$-manifold. We give an example and investigate the integrability conditions for the distributions involved in the definition of a semi-invariant submanifold of an almost $\alpha$-cosymplectic $f$-manifold.
